Servings 6 servings

Ingredients

  

• Olive oil – for sautéing
• Italian sausage (mild or hot, casings removed) – about 1 pound
• Yellow onion – 1 medium, diced
• Garlic – 4 cloves, minced
• Crushed red pepper flakes – optional, for heat
• Italian seasoning – or dried oregano and basil
• Russet or gold potatoes – 3–4 medium, sliced into half-moons
• Chicken broth – about 6 cups (low sodium preferred)
• Sun-dried tomatoes (in oil, drained and chopped) – 1/2 cup
• Heavy cream – 1 cup (or half-and-half for lighter)
• Parmesan cheese – 1/2 cup, freshly grated
• Baby spinach or chopped kale – 4 cups loosely packed
• Lemon – 1, for juice and optional zest
• Salt and black pepper – to taste
• Fresh basil or parsley – optional, for garnish

Instructions

 

• Brown the sausage: Heat 1 tablespoon olive oil in a large pot over medium-high heat. Add the sausage, breaking it up with a spoon. Cook until browned and no longer pink, about 5–7 minutes. Spoon off excess fat if needed, leaving about 1 tablespoon for flavor.
• Sauté aromatics: Add the diced onion and a pinch of salt. Cook until soft and translucent, 3–4 minutes. Stir in the garlic, red pepper flakes, and Italian seasoning. Cook 30–60 seconds until fragrant.
• Add potatoes and broth: Stir in the potato slices to coat with the aromatics. Pour in the chicken broth and add the chopped sun-dried tomatoes. Bring to a gentle boil, then reduce to a simmer.
• Simmer until tender: Cook uncovered for 12–15 minutes, or until the potatoes are fork-tender. Stir occasionally to prevent sticking. Taste and season with salt and pepper as the flavors concentrate.
• Make it creamy: Reduce heat to low. Stir in the heavy cream and Parmesan until melted and smooth. Keep the soup below a simmer to prevent the dairy from separating.
• Add greens: Fold in the spinach (or kale). Cook just until wilted, 1–2 minutes for spinach or 3–4 minutes for kale. If the soup is too thick, add a splash of broth or water.
• Brighten and serve: Squeeze in 1–2 teaspoons of fresh lemon juice. Taste and adjust salt, pepper, and heat. Ladle into bowls and garnish with fresh herbs and a little extra Parmesan.

Why This Recipe Works

Save

This soup layers flavor from the start by browning sausage and sautéing aromatics, building a savory base without needing fancy ingredients. Potatoes simmer in the broth until tender, naturally thickening the soup and giving it body.

Cream and Parmesan add richness, while sun-dried tomatoes and a splash of lemon keep it lively. Spinach (or kale) brings color and nutrients without extra work. It’s hearty but balanced, creamy but not heavy, and ready in under an hour.

Step-by-Step Instructions

1. Brown the sausage: Heat 1 tablespoon olive oil in a large pot over medium-high heat.

   Add the sausage, breaking it up with a spoon. Cook until browned and no longer pink, about 5–7 minutes. Spoon off excess fat if needed, leaving about 1 tablespoon for flavor.

2. Sauté aromatics: Add the diced onion and a pinch of salt.

   Cook until soft and translucent, 3–4 minutes. Stir in the garlic, red pepper flakes, and Italian seasoning. Cook 30–60 seconds until fragrant.

3. Add potatoes and broth: Stir in the potato slices to coat with the aromatics.

   Pour in the chicken broth and add the chopped sun-dried tomatoes. Bring to a gentle boil, then reduce to a simmer.

4. Simmer until tender: Cook uncovered for 12–15 minutes, or until the potatoes are fork-tender. Stir occasionally to prevent sticking.

   Taste and season with salt and pepper as the flavors concentrate.

5. Make it creamy: Reduce heat to low. Stir in the heavy cream and Parmesan until melted and smooth. Keep the soup below a simmer to prevent the dairy from separating.
6. Add greens: Fold in the spinach (or kale).

   Cook just until wilted, 1–2 minutes for spinach or 3–4 minutes for kale. If the soup is too thick, add a splash of broth or water.

7. Brighten and serve: Squeeze in 1–2 teaspoons of fresh lemon juice. Taste and adjust salt, pepper, and heat.

   Ladle into bowls and garnish with fresh herbs and a little extra Parmesan.

How to Store

Let the soup cool until just warm, then transfer to airtight containers. It keeps in the fridge for up to 4 days. The potatoes will continue to soften, which makes the soup even creamier the next day.

Reheat gently on the stove over low heat, stirring occasionally. If it thickens too much, add a splash of broth or water to loosen it. For freezing, skip the dairy and greens, freeze up to 2 months, then add cream and spinach when reheating.

Health Benefits

• Leafy greens: Spinach or kale adds iron, vitamin K, and antioxidants with almost no extra calories.
• Potatoes: A natural source of potassium and fiber, especially if you leave some skin on.
• Protein: Sausage provides protein for satiety.

  You can swap in chicken sausage or turkey sausage to reduce saturated fat.

• Balanced meal: This soup brings together carbs, protein, and fats, making it satisfying without needing sides.
• Customizable richness: Use half-and-half or evaporated milk for a lighter option while keeping the silky texture.

What Not to Do

• Don’t boil after adding cream: High heat can cause the dairy to split. Keep the heat low once cream is in.
• Don’t skip seasoning layers: Taste after the potatoes cook, after the cream, and before serving. Small adjustments make a big difference.
• Don’t crowd the pot with raw greens: Add them at the end in batches so they wilt evenly.
• Don’t overcook the potatoes: Mushy potatoes can cloud the broth.

  Aim for just-tender.

• Don’t use pre-shredded Parmesan: It often contains anti-caking agents and doesn’t melt as well. Freshly grated blends seamlessly.

Variations You Can Try

• Chicken Tuscan: Swap sausage for diced rotisserie chicken. Sauté onions and garlic in olive oil, then continue as written.
• Vegetarian: Use vegetable broth, replace sausage with cannellini beans, and add a teaspoon of smoked paprika for depth.
• Lighter dairy: Use half-and-half or a mix of milk and a tablespoon of cream cheese for body.
• Extra veggies: Stir in sliced mushrooms with the onions, or add diced zucchini during the last 5 minutes.
• Spicy kick: Use hot Italian sausage and increase red pepper flakes.

  Finish with a drizzle of chili oil.

• Kale and white bean: Add a can of drained cannellini beans when you add the broth for extra protein and fiber.
• Gluten-free and grain-free: This soup is naturally gluten-free. Just check labels on broth and sausage.
